RENEWABLE

Waves are created by the wind blowing across the sea and by the gravitational force of the moon. Wave power uses the energy of the waves to turn turbines that make Electricity. l

Geothermal power uses the heat that comes from deep rocks under the surface on the Earth increases towards its centre. The hot water or steam that comes from deep within our planet can be used to make electricity. l

Hydro-electric is generated from running water. Dams are built across a lake or river In a valley to trap water. The water flows through tunnels and turns the turbines which make electricity. l

Solar The sun releases an amount of energy due to the nuclear fusion of hydrogen taking place within its core. Solar panels, called photovoltaic cells are used to convert the Sun energy into electricity. The sun’s can also be used to heat water passing throungh special solar collectors.

Wind l Wind is made when the Sun heats the Earth and the area above land gets hotter than the area above water. The hot air above land rises upwaras leaving an area of low pressure. Cooler air moves into this areaof low pressure making wind which we use to turn wind turbines and make electricity. Wind used to be used to turn windmills to grind wheat into flour.

Biomass uses the energy from plants and waste materials to make electricity. For example, wood or anima droppings can be burnt to make steam that turns turbines to make electricity. l
